Specifications 14 N F R A R E D Introduction The MS-1 is a miniature IR sensor designed for use with the Niles Infrared Repeating systems. Installed in a remote room location, the MS-1 receives the IR commands transmitted from your existing hand-held remotes in that room.
Printed circuit board design uses surface mount technology (SMT), assuring high reliability. Ideal for both home and commercial installations. Bezel colors: Each MS-1 includes a black and white bezel. Two year parts and labor warranty. Proudly made in the USA.
• 1/8" Standard Slotted Screwdriver MS-1 Mounting Location The MS-1 is ideal for use in applications when tabletop, ceil- • Adjustable ing, or wall-mounting is undesirable. Its small size and unob- wrench or pliers trusive appearance makes it ideal for installation in obscure, •...

Infrared signals travel essentially line-of-sight. They will not pass through or around solid objects. Do not rely on an IR signal being able to "bounce" off a wall or object to the MS-1. The IR pickup angle of the MS-1 is 60 off-axis (horizontal and vertical) at 18 feet.

If you are installing the MS-1 near a television, keep it at least 6" away from the top, bottom or sides of the TV to avoid interference.

E N S O R Avoiding Optical Feedback If installing the MS-1 in the same room as an IR flasher, it is possible for the flasher's IR output to be picked-up by the MS-1. This effect, known as an optical feedback loop, can cause erratic operation.

The MS-1 is supplied with 10' of pre-stripped IR cable. The IR cable may be shortened or lengthened as needed. If you want to make the MS-1's cable shorter, use a pair of wire cutters to cut the cable to the desired length. The IR cable may be lengthened by splicing it to a recommended IR cable (See Installation Considerations —...

Operation of the MS-1 is straightforward. Simply aim your hand-held remote at the MS-1. Your IR command is instantly repeated to your A/V equipment. A green "flash-back" LED on the MS-1 visually confirms the presence of an IR signal. Figure 3 MS-1 Operating...
The LED should light only when a remote command is being received. If the MS-1 does not work, and the LED does not light at all: 1. Test the remote control(s) by operating the A/V equip- ment directly. Replace the batteries if needed.

There are many methods for reducing interference. Which solution is best for you depends on your situation. Contact Niles Technical Support at 1-800-289-4434 if you require further assistance. If the LED on the MS-1 "flickers" dimly, and the MS-1 functions normally, there is no cause for concern.
